Specification of Letters Patent.

DISINFECTING DEVICE Patented March 16, 1909.

To all whom it may concern:

Be it known that we, SVEN A. SHIPP and LAWRENCE LUND, of Minneapolis, Hennepin county, Minnesota, have invented certain new and useful Im rovements in Disinfecting Devices, ol whic i the following is a speciiication.

Our invention relates to disinfecting apparatus and particularly to the means for delivering the disinfecting material at predetermined intervals.

The invention consists generally in means controlled by the movement of a tank float for delivering a quantity of the disinfecting material at predetermined intervals of time.

In the accompanying drawings, forming part of this specication, Figure l is a front elevation of a water closet tank with the wall broken away illustrating the application of our invention thereto. Fig. 2 is a plan view of the apparatus for delivering the disinfecting material. Fig. 3 is a side elevation illustrating the means for securing the device on the tank. Fig. 4 is a sectional view of the drum or receptacle in which the disinfecting material is placed. l

In the drawing, 2 represents a water closet tank having the usual float 3 for controlling the admission of water thereto.

i is a frame and 5 a bracket secured to the wall ofthe tank and having slots 6 and screws 7 assing therethrough into said frame, and w ereby said frame is rendered vertically adjustable on the tank. 8 is a drum having pivots 9 in said frame and provided with a discharge opening 10 on one side that is normally covered by a valve l1 having a spring closing device 12. Till/'hen this valve is opened a disinfecting material is allowed to fall out by gravity into the tank 2. A stop 13 is provided on the frame in the path of the valve 11 so that when the drum revolves and passes the stop the valve will be swung open and the contents of the drum allowed to fall out. As soon as the valve has moved past the sto the s ring device will close the valve and ho d it s ut until the drum makes another revolution.

To revolve the drum we provide a ratchet wheel 14 on one of the pivots 9 and mount a bail l5 on the said pivots, said bail having a dog 16 that enga es the teeth of the ratchet wheel 14 and is eld in engagement therewith by a spring 17. A dog 18 prevents backward movement ofthe ratchet wheel. When the bail is oscillated up and down the ratchet wheel will be revolved and the drum will turn with. it. A float 19 is provided in said tank having a stem 2O provided with a series of holes 2l and a screw 22 passes through said bail and through one of the holes 2l in the stern 20, and by shifting the position of the screwin the stem the elevation of the oat in the tank can be changed according to the amount of water therein or the time of movement desired tor the drum.

A bracket 23 depends from the frame 4 and a link 24 pivotally connects the said bracket with the stem and serves to guide the stem and bail in their up and down movement. A lug 25 serves to limitthe'downward movement of the bail l5 and a plate 26 is mounted on the pivot of the drum and is adjustable by means ol a slot 27 and screw 28, and has a lug 29 which overhangs the bail and limits its upward movement. By the adjustment of this plate the up stroke of the bail may be regulated and the dog 16 allowed to slide over one or more of the teeth of the ratchet wheel as desired.

In operation, water entering the tank will raise the float 19 and with the upward movement of the tloat the dog 16 will slide over the ratchet and when the iioat descends as the water recedes the ratchet wheel and the drum will be revolved a step and this moveinent will continue with each operation of the lloat. `When the valve 11 arrives opposite the stop on the frame and is actuated thereby a portion of the contents ofthe drum will be allowed to drop out in the water in the tank. As soon as the valve has moved by the stop its spring will close it and the drum will continue its revolution as the lloat is raised and lowered. n

`We claim as our invention:

1. The combination, with a tank, of a revolving drum adapted to contain a disinfecting agent and having a suitable discharge opening and a valve therefor, a loat connected with said drum and arranged to revolve it with a step by step movement, and means for opening said valve at a predetermined oint in the revolution of said drum to disc arge a portion of said disinfecting agent.

2. The combination, with a tank, of a revolving receptacle having a discharge opening and a normally closed valve therefor, means for opening said valve at a predetermined point in the revolution of said receptacle, ,and .means for ,operating said receptacle. .A i, '3. The combination, with a 'Water closet 5 tank, of a revolving receptacle adapted .to contain a disinfecting agent and having `a feed 4opening, .a valve V,normally ,closing V said opening, means for opening said valve at predetermined intervals, and a float connected lo With said receptacle and having an up and down movement, and mechanism whereby said receptacle Will be revolved step by step VWithlthe movement of said float.

4l. The combination, With a tank, of a 15 revolving receptacle thereon having a feed Aopening` and a valve therefor, means for opening said valve once With every revolution .of'said receptacle, `a Aoat, ,and mechanism ,connecting ,said oat With said drum, 20 Swhereby,uponthe movement of said float a .rotary ;rnovernent -will Lbe imparted to said drum.

f5. The combination, With a tank, of a 4drum 'having a feed .opening and" a lvalve 25 therefor, means `for o ening said valve at predetermined interva s, an* oscillating bail,

a .ratchet Wheel, a dog mounted on said bail .and .adapted to engage the teeth of said ratchet, a float adjustably connected Withsaid `'loailand' adapted to rise andfall therewith, 30

the upward movement of said bail causing the dog to slide over the teeth of said ratchet,

` and Ithe Weight of said float returning said bail -to its normal position and revolving said ratchet and drum, substantially as described. S5

6. The combination, With a tank, of a revolving drum having a feed opening and Aa valve therefor, means for opening said valve at predetermined intervals7 an oscillating' bail having a ratchet connection with said 4o SVEN A. SHIPP. LAWRENCE LUND. lv/Witnesses:
